MACHINE FOR IPRIEPARING INEJOLES.

To all 107mm 1'6 may concern:

Be it known that I, Gnoncn 1G. Romans, a citizen of the United States,residing at Brockton, in the county of Plymouth and State of hIfassachusetts, have invented new and useful Improvements in Machinesfor Preparing Insoles, of which the following is a specification.

This invention relates to machines for preparing insoles, the objectbeing to provide a machine for more efficiently tucking the reinforcingmaterial of an insole into the angles where the lip of the insole joinsthe marginal feather.

The machine is designed to operate upon an insole to which thereinforcing material has been stuck preferably by cement, but which hasnot the reinforcing material tucked into the angles as closely as isnecessary. One instrmnentality of the present machine engages the freeedge of the lip and bends the same inwardly, thus drawing thereinforcing material away from the feather. This instrmnentality holdsthe lip while a second instrumentality tucks the re inforcing materialinto the angle at the junction of the lip and feather, said tuckingmember having imparted thereto, in addition to its inward and outwardmovement, a lateral movement which is utilized for feeding the work andcausing a portion of said tucking member, which engages said work, to bemoved in an elliptic path. Furthermore said tucking member is adapted topress said reinforcing material upon the marginal feather and to bendsaid feather away from said lip in order to shape the insole so thatthere may be more space for the needle of a sewing machine when saidinsole is subsequently attached by sewing to the upper of a boot orshoe.

In addition to the above instrmnentalitics a third instrumentality isprovided to engage the inner side of the lip and to tuck the reinforcingmaterial thereof into the angle at that side and to support said lipduring the actions of said bending and tucking instrumentalities.

The invention consists in the combination and arrangement of partswhereby the above object and certain other objects hereinafter appearingmay be attained, all of which are set forth in the followingspecification and particularly pointed out in the claims.

Referring to the drawings: Figure 1 is a vertical section, partly inelevation, in a plane from front to rear of a machine embodying myinvention, a portion of an insole being illustrated in connectiontherewith and the several working parts of said machine beingillustrated in operative positions. Fig. 2 is a plan view of a portionof the gearing of said machine. Fig. 3 is a detail plan view of theouter tucking and feeding instrumentalities together with other elementsof the mechanism closely associated therewith. Fig. 4: is a plan view ofan adjustable holder for the lip bending instrumentz'ility. Fig. 5 is avertical section partly in elevation through the adjustable structurewhich supports and drives the outer tucking instrumentality, lookingfrom the rear of said machine. Figs. 6, 7 and 8 are enlarged sections ofan insole illustrating the condition of the same before, during andafter it has been treated by the present machine. F 9 is a verticalsection through the work gaging instrumentalities and the means fordriving the same, said section being taken on a plane similar to that towhich Fig. 1 is taken on a somewhat enlarged scale.

Trike numerals refer to like parts throughout the several views of thedrawings.

The frame of the machine is indicated at '10, and it is provided withsuitable bearings ll. for :1 Prime Power shaft '12. The shaft isprovided with the usual pulleys 13 and 13, one of which is tight and theother loose. A vertically movable work support is indi rated at 14..This support is circular and has a transverse top surface 15 and abeveled marginal surface 16, which surfaces are provided for engagingrespectively the flat body portion X and the marginal feather X of aninsole. The work support is intended to rotate about a vertical axis,and for this purpose it is provided with a cylindric hub or stem LT, andthis stem is mounted in a sleeve 18. The work support is atlixed to thesleeve, and the sleeve is mounted in suitable bearings 15) in the frameand is adapted to rotate to move ver tic-ally in its bearings. A wormgear 90 splined upon the sleeve and is disposed between the bearings 19.This gear is driven by a worm 21 on the shaft 12. The work support isnormally elevated by a compression spring 22 disposed in the sleeve, the

upper end of the spring bearing against the hub 17, and the lower endbearing against an adjustable abutment 23. This abutment is adjusted bymeans of a screw 24 engaging the frame 10. A spool 25 mounted upon thesleeve is engaged by a forked lever 26, the latter being mounted upon afulcrum stud 2? and being provided with a treadle rod 28 whereby thework support may be depressed against the force of its spring when thetreadle rod is depressed. The spool is adjustable relatively to thesleeve and rests upon a collar 29 which is adj ustably secured to thesleeve by a set screw 30. This collar will be adjusted according to thethickness of the soles upon which the machine is to operate, to the endthat the force of the spring 22 may be used to force the insole againstthe instrumentalities which act upon the material a with which theinsole is reinforced.

The tucking tool which operates upon the inner side of the lip X isindicated at 31. V

The end of this tool is pressed by a spring against the reinforcingmaterial on the flat part of the sole, this pressure being constant,while at the same time the tool is rotated about its axis for thepurpose of assisting in feeding the work. The tool is preferably made intwo parts, the part indicated at 31 being the work-engaging part, andthe shank indicated at 32 constituting the main body of the tool. Thejoint indicated at 33, whereby the two parts are joined, comprises amale threaded portion on the part 32 and a threaded socket in the part31, the screw thread being a left-hand thread in this instance becauseit is desired to have the threaded parts automatically tightened whenrotation is in the direction of the arrow. The shank 32 is mounted in asleeve 34, and its upper end has a sliding fit in a bushing 35 which isscrew-threaded in the sleeve. The function of this bushing is tocompress a helical spring 36 whose lower end engages a collar 37 affixedto the shank 32. The sleeve 34 is mounted and rotatable in a stationarybearing 38 which is an integral or attached part of the frame 10. Thebearing 38 is recessed for the reception of a helical gear 39, whichgear is connected to the sleeve 34 by a spline 40. Hotation is impartedto the gear 39 from a gear 41 by an intermediate gear 42. The gear 41 isaflixed to the upright shaft 43 which has at its lower end a spiral gear7 2 intermeshing with a spiral driving gear 73 on the shaft 12. Rotationof the sleeve34 is transmitted to the shank 32 by a pin 44 connectingthe two, the sleeve 34 being slotted at 34 to permit slight yielding ofthe tool 31. The sleeve 34 is held against longitudinal movement bycollars 45 which have set screws 46.

The shape of the tool 31 is such as to tuck the reinforcing materialsnugly into the angle of the sole and the inner side of the lip X andalso to enable the lip lean inwardly, as shown by Figs. 7 and S. The lipis bent inwardly, as shown, by roll 47 which is rotatable, the members31 and 47 cooperating in such manner as to pinch the lip and cause itto. assume an inclined position; The work-engaging surface of the roll47 is frusto-conical and engages the lip at the extremity of the latterbut not otherwise. This roll is loosely mounted upon a spindle 48 whichis affixed in a holder 49. A pinion 50 is compounded with the roll andis driven by a gear 51 through an intermediate gear 52. The gear 51 isaffixed to a shaft 53 which is mounted in a swinging carrier 58. Thisshaft extends through an elongated hole 55 in the holder 49, this holepermitting adjustment of the roll 47 toward and from the tool 31. Therear end of the holder 49 is formed with a recess 56 which is occupiedby a stud 57, the stud being affixed to the aforesaid carrier 58. Thestud 57 has a shoulder 59 which the bottom surface of the holder 49 andclamping nut 60 which engages the top surface,- the aforesaid recesspermitting adjustment of the holder, and the shoulder 59 and nut 60serving to clamp the holder rigidly with relation to the swingingcarrier 58.

The carrier 58 supports a forming-in tool 61 which has a wiping actionupon the feather X and which tucks the reinforcing fabric into the angleof the lip and the feather. The forming-in tool is mounted upon aneccentric 62 carried by the shaft 53. The rear end of the tool isforked, as indicated at 63, and straddles the stud 57, the stud servingas the fulcrum of the tool and the tool receiving a forward and backmotion combined with a lateral motion whereby the work-engaging portionis caused to describe an elliptic path. This tool engages the bottom ofthe roll 47 and holds the roll on its spindle 48, the two work-engaginginstrumentalities being contiguous, and the spindle 48 serving to keepthe tip of the tool 61 pressed downwardly against the feather of theinsole. The under surface of the tool 61 is substantially par allel tothe adjacent portion of the surface 16 of the work'table, these twoconfronting surfaces being at an angle to the main portion of the worktable and therefore adapted to bend the feather to the position shown byFig. 8. The feather is thus bent away from the lip X and the lip is bentaway from the feather, the separation of the lip and feather causing thereinforcing material to. pulaway from the bodies of the lip and thefeather as shownby 7. While the reinforcing material is thus freed fromthe feather for the greater portion of the width of said feather, theforming-in tool 61 is thrust forward, thus entirely freeing and carryingthe reinforcing material into the angle and drawing the edge of thereinforcing material inwardly within the margin of the feather, as shownby Fig. 8 it being understood that although the outer margin of thereinforcing n'iaterial may be engaged by the under surface of the tool(3] just prior to the inward or fcrward movement of said tool, thepressure at such a time upon said material would not be sutlicient toprevent said reinforcing material from being drawn iiiwardly relativelyto said feather and at which time said reinforcing material will beei'itircly freed or detached from the surface of said feather, but stillin contact with a portion thereof. The lateral movement of the tool 61causes the forward edge to score the reinforcing material for a shortdistance along the angle, which the bottom surface of the tool continuesto press against the feather. By thus freeing the reinforcing materialfrom the feather prior to tucking it into the angle, the forming-in tooldraws the reinforcing material inwardly from the edge of the soleinstead of drawing the reinforcing material from the lip toward thefeather. The forming-in of the reinforcing material does not stretchthat portion which covers the lip, and consequently when the sole isremoved from the machine there is no tendency on the part of thereinforcing material to pull the lip toward the feather nor to pull thefeather toward the lip, and these parts are adapted to remain bent, asshown by Fig. 8.

As shown by Figs. 3 and 5, the carrier 58 is mounted to swing upon afulcrum stud 54lwhcreby it is connected to a bracket 1O or otherstationary part of the frame 10, the axis of the stud being parallel tothe axis of the shaft The purpose of the swinging movement is to permitretraction of the tools .157 and 61 when inserting and removing the workand also for the purpose of keeping the roll 47 against the lip when themachine is in operation. A spring for the aforesaid purpose is indicatedat (wt in Fig. One end of this spring is inserted in a suitable socketin the airrier, and the other end is inserted in an adjustabli screw(35. This screw is threaded in the frame 10 and is adapted to cause thespring to act with more or less force. The carriru: extends to theopposite side of the shaft 5; and fulcrum stud 54- and is formed with asocket for the reception of one end of a pin (36 which transmits motionfrom a bell-crank (37 mounted upon the stud 27. A. treadle rod (38 is zttached to the bell-crank and when depressed it swings the tools l and(51 away from the work and about the axis of the stud 5a.

The lower end of the shaft 53 provided with a spiral gear 6i) which isdriven by a spiral gear on the main shaft 12 through an intermediategear 71 mounted upon the fulcrum stud 54-.
